Billionaire innovator Elon Musk has confirmed that Tesla is still working on an electric semi truck, but stressed that the company's primary focus for this year will continue to be on the Model 3.

With the electric semi truck dubbed "Tesla Semii," Tesla wants to appeal to a larger audience. If the company successfully manages to place an electric semi truck in the cargo industry, then the costs of shipping can be significantly decreased globally.

Tesla CEO Elon Musk has confirmed that the e-car company is testing Autopilot safety features through a software update rolled out to one thousand vehicles that have been built with fully-autonomous hardware.

After October 2016, Tesla built its e-cars with fully-automated hardware, called "Hardware 2." The new update equipped these vehicles with the Autopilot semi-autonomous features. These vehicles will eventually become fully self-driving. The update also added a few Autopilot safety features to the vehicles.

In a blog post published on Thursday, electric vehicle manufacturer Tesla Motors said that it will be charging a global "idle" fee from vehicle owners who park their vehicles too long at a Supercharger. The company said that it would charge $0.40 per-minute from vehicle owners who keep their car parked at a Supercharger even after it has completed charging.

The move, Tesla said, is being undertaken by the company to ensure that its Supercharger network is not misused.

The SolarCity acquisition deal, worth approximately $2 billion, was closed by Musk after Tesla shareholders -- assembled at the company's manufacturing facility in Fremont, California -- gave their approval to the move on Thursday.

In a Monday announcement, electric vehicle maker Tesla has revealed that, with effect from January 2017, the company will give up on free charging at its international network of Supercharger stations.

The announcement implies that, from next year onwards, charging at Tesla's Superchargers will not be free any more. As such, new Tesla buyers who want to plug in their electric vehicles at the Superchargers will have to pay a fee.

In a Wednesday announcement, electric vehicle manufacturer Tesla Motors' CEO Elon Musk revealed that all new Tesla vehicles will be equipped with self-driving hardware, so as to eventually make the vehicles fully autonomous.

According to the details shared by Musk, all the new vehicles manufactured by Tesla will be retrofitted with radar, eight cameras, and 12 ultrasonars, as well as a supercomputer which has the capability to process data 40-fold faster than before.

In its filing with the U.S. Securities Commission on Friday, Israeli firm Mobileye - a company known for its vision systems for vehicles - accused its former partner Tesla Motors of allowing the drivers of its electric vehicles to drive hands-free while using the 'Autopilot' driving assistance system even despite Mobileye's objections.
